Nuclear Magnetic Resonant Imaging (also called Magnetic Resonant Imaging or “MRI”) devices which are implantable, internal or insertable are provided. The disclosure describes ways to miniaturize, simplify, calibrate, cool, and increase the utility of MRI systems for structural investigative purposes, and for biological investigation and potential treatment. It teaches use of target objects of fixed size, shape and position for calibration and comparison to obtain accurate images. It further teaches cooling of objects under test by electrically conductive leads or electrically isolated leads; varying the magnetic field of the probe to move chemicals or ferrous metallic objects within the subject. The invention also teaches comparison of objects using review of the frequency components of a received signal rather than by a pictorial representation.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method of claim 1, wherein the frequency scans of the received signal is performed by a panoramic receiver.
3. The method of claim 1, wherein the frequency scans of the received signal is performed by Fast Fourier Transform Analysis of a received waveform.
4. The method of claim 1, wherein the frequency scans of the received signal is performed by a receiver tuned by a ramp generator.
5. The method of claim 4, wherein the ramp generator is an analog ramp generator.
6. The method of claim 5, further comprising frequency sweeping of the received signal by a saw tooth oscillator across a frequency band.
7. The method of claim 6, wherein the frequency sweeping occurs at 100 KHz to remove artifact situations.
8. The method of claim 1, further comprising bypassing pictorial representation, and using Fourier transform, or panoramic or spectrum analysis by an analog ramp generator to do magnetic resonant imaging.
9. The method of claim 1, wherein the frequency scans comprise radio frequency scans for displaying a radio frequency waveform non-pictorially.
10. The method of claim 1, further comprising generating a main magnetic field for rotational displacement within the magnetic resonance image (MRI) device which performs the magnetic resonance imaging.
11. The method of claim 10, further comprising generating additional gradient magnetic fields within the magnetic resonance image (MRI) device.
